100 kva three phase oil type distribution transformer

Qianlai Electric’s 100 kva three phase oil type distribution transformer are primarily designed for small and medium-sized users and distribution substations with loads around 80kW, requiring stable performance and outdoor installation capabilities. Featuring robust construction and excellent insulation, these transformers are well-suited for outdoor environments. While maintaining quality standards, Qianlai Electric has also optimized the design to reduce costs, delivering greater value to customers.

How to Prevent 100 kva three phase oil type distribution transformer Fires

100 kva three phase oil type distribution transformer are filled with mineral insulating oil produced through distillation and refining, which is flammable. Therefore, fire prevention is particularly important during transformer installation and maintenance.

Keep the site clean
The substation site shall be clearly zoned. In the transformer installation or maintenance area, all open flames and heat sources (such as heaters, cigarette ends) must be removed. Hot work is prohibited in the operating area. Unauthorized personnel are not allowed to enter.
Remove oil mist in a timely manner
Maintain good ventilation in the operating environment and discharge oil mist promptly to prevent the accumulation of flammable gases.
Control the oil filling speed
When filling oil into the transformer, control the speed to avoid splashing.
Ensure stable earthing
Static electricity may generate sparks and cause fires. Earthing is essential for anti-static protection.
The transformer must be earthed immediately after installation, and all related equipment shall also be earthed to discharge static charges to the ground.
24-hour monitoring
Implement closed management and 24-hour monitoring of the operating area, check the oil level in real time, and observe for any oil overflow.
Adequate fire-fighting equipment
Fire-fighting equipment must be provided in the transformer installation or maintenance area with clear responsibility assigned to personnel. Operators shall conduct regular drills as required.
